Developer Young Horses has released two new levels, or 'shorts' as the team calls them, for slapstick physics-based game Octodad: Dadliest Catch.

'Dad Romance' and 'Medical Mess' continue the story of the base game, and are available for free to all owners. There's also a bunch of other additions, including multiple mice support for co-op and temporary checkpoints for levels.

Have you ever wanted to be an Octodad? Good news friend, thanks to the facial motion software Facerig, which maps your face onto animated characters allowing you to manipulate their movements, you can live your dream.

Developer Young Horses, the team behind madcap puzzle game Octodad: Dadliest Catch, let Facerig load their hapless hero into the software, and the result is strangely impressive.

The nine-man developer Young Horses worked on Octodad: Dadliest Catch "for free" for two-and-a-half years, reveals a blog. They held down other full-time jobs to keep Octodad running, or 'squiding' or whatever.

To date, Octodad: Dadliest Catch has sold over 90k copies for PC, Mac and Linux. It has blown Young Horses socks right off, which I guess would be horseshoes?
